5306, NSK, double-row angular contact ball bearings, Bore diameter: 30 mm; Outside diameter 72 mm; Width 30.2 mm.

NSK 5306 bearing is basically a back-to-back of two single-row angular contact ball bearings, but their inner and outer rings are each integrated into one. So axial loads in both directions can be sustained, and the capacity to sustain moments is good.
